MNG navicn Application filed Decembert, 1922, Serial No. 605,918. Renewed December-r 10, 1928.

To all whom it may concern: Be it known that I, WILLIAM E. i. a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented new and useful. Im-

provements in Mixing Devices, of which the ollowing is a specification.

This invention relates to mixing devices and has for its object the provision of a w novel device designed primarily for use at soda fountains and the like, thou h not necessarily confined to such use, or the purpose of mixing malted milk, egg or similar drinks, milk shakes. and the like.

An important object is the provision of a device of this character which combines in one machine three machines either of which maybe used alone, any two of which may be used or all of which may he used simultaneously, the device in this way combining the advantages of three separate ordinary devices while taking up less room on the fountain or counter.

Another object is the provision of a device of this character which is provided with an electric motor which furnishes the power and which has clutch controlled drive connections with the various mining elements, the clutch means being so constructed that it automatically operates control switches for appl ing power to the motor or cutting o the power as the case mayloe. An additional ohiect is the provision of a device of this character which will be simple and inex ensive in manufacture, neat and attractive 1n appearance, rapid in action, eficient and durable in service and a general improvement in the art.

With the above and other objects and ad- I vantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the device,

Figure 2 is a vertical section taken in a plane parallel with the front,

Figure 3 is a vertical section taken at ri ht angles to Fi re 2,

igure 4 is a orizontal section,

Figure '5 is a vertical section similar to Figure 3 but taken at the opposite of the S nd rd be stirre b Figure 6 is a diagram of the electricv circuit and Fi re 11116 of Eigure 4. 7

Referring more particularly to the drawings I have shown my device as comprising a hollow standard 10 rising from a suitable base 11 and carrying a casing 12 within which is mounted all the transmission mechanism to be described. V

Vertically adjustably mounted upon the standard 10 is a bracket 13 carrying a platform 11 designed to support a glass or other receptacle containing a mixture to be agitated or shaken by one of the elements of the device. Extending from the opposite side of the standard is a guide 15 against which may he laced a receptacle of mixture to another element of the device and depending from one end of the casin 12 is an arm 16 provided with a guide 1% similar to the guide15 and against which may be placed a receptacle containing a mixture to be stirred by the remaining mixing element to be described.

On the standard 10 and arm 16 are clips 19 for engagement over the edge of a glass or other receptacle used for preventing overturning thereof.

Suitably mounted within the casing 12 is an electric motor 18 of any preferred type and of any necessary power and the lead wires 19 to this motor are brought down through the hollow standard 10 for the pur ose of convenience. lhe motor shaft 2011s prolonged so as to extend along the ma'or portion of the casing 12 longitudinal y thereof at substantially its center and secured upon one end of this shaft is a small friction disk 21 while securedto the other end are two spaced similar disks 22 and 23.

Located within this portion of the casing which overlies the platform 14 is a partition or bearing portion 24 through which is rotatably and slidably mounted a shaft 25 upon the lower end of which is journaled a friction disk 26 disposed below. and designed to co-operate with the disk 21. carried by and journaled through this disk 26 is a depending spindle 27 which has its lower end carrying a heater 28 and which' has its upper end carryinga spur pinion 29 meshing with a similar. plan 30 when is 7 is a detail sectional view on thetill Edit

rigidly secured on the'underside of the partition 24. The bottom of the casing overlying the platform 14 must be partly open so as to permit the rotary as well as spinning action of the spindle 27 as will be obvious.

Mounted within this end portion of-the casing is a bearing bracket 36 through which is journaled a stem 31 which has its forward end projecting beyond the casing and carrying a control knob 32. Beneath this stem is a block member 33 carried by the upper end of the shaft 25. Encircling the shaft is a coil spring 34 which abuts against a member 33 and against a sleeve bearing 35 through which the shaft 25passes. Secured on the stem 31 is a cam 36 engaging the member 33 so that when the knob 32 is turned to the left the member 33 will be forced downwardly against the resistance of the spring 34 carrying with it the disk 26 and beater structure carried thereby so that engagement between the disks 21 and 26 will be broken.

Located in the other end portion of the casing and rising from the bottom thereof are bearings 37 and 38 within which are rotatable bushings 39 and 40 within which again are eccentrically journaled depending stems 41 and 42 which are similar. These stems project downwardly to a considerable extent below the casing and have their lower ends carrying whirling disks 43 and 44. respectively. designed to be received within receptacles disposed against the guides 15 or 17 respectively. The bushings 39 and 40 carry arms 45 and 4,6. Secured upon the upper ends of the stems 41 and 42 are friction disks 49 and 48 adapted to bear against the disks 22 and 23 respectively and it will be observed that the bushings are cut away at one side to accommodate these small friction disks. I

Journaled through the front of the casing are stems 51 and 52 carrying' operating knobs 53 and 54 and also carrying cams 55- and 56 respectively engageable with the arms 45 and 46 whereby to rock the bush ings to a sufiicient extent tobring the disks 49 and 48 into engagement with the associated disks 22 and 23.

I provide a control switch device associated with each of the stems 31, 51 and 52 and each of these switch devices consists of a supporting block 57 of insulating material carrying a stationary contact 58 with which is engageable a movable contact 59. All the contacts 58 are connected with one of the wires leading to the motor while each of the contacts 59 is connected with one terminal of the motor, the other terminal of the motor being connected directly to the power line as shown in the diagram. In other words these three switch devices are in parallel. The stem 31 carries a cam 60 which engages the contact 59 of the associated switch for closing the circuit to the motor when the knob 32 is turned to bring the disk 26 into engagement with the drive disk 21. The stems'51 and 52 carry cams 61 and 62, respectively, Which are engageable with the contacts 59 of the associated switch devices when the knobs 53 and 54 are turned to throw the disks 49 and 50 into engagement with the disks 22 and 23.

In the operation it will be seen that a glass or other receptacle containing ingredients to be mixed may be placed upon the platform 14 in such a way that the beater 28 will be within the glass. By then turning the knob 32' to the right, the disk 26 will be engaged with the disk 21 and the motor will be energized so that the beater 28 will operate to mix the materials.

In a similar manner, receptacles containin mixtures may be "placed beneath the spindles 41 and 42 against the guides 15 and 17 and the knobs 53 and 54 turned to the right to engage the disks 49 and 50 and to close the circuit through the motor. The rotation of the disks 43 and 44 carried by the spindles 41 and 42 will operate to mix toget er the materials. It will be noted that either one of the mixing devices may be used alone, any two maybe used at the same time or all may be operated simultaneously. The device thus operates to combine in one apparatus the functions of three and consequently saves space on a counter. or soda fountain. Owing to the automatic making and breaking of the control circuit when the operating knob is turned to throw-in either one of the mixing devices it is apparent that the operation and control is greatly simplified and that auxiliary switches will be entirely unnecessary, while at the same time waste of current will be prevented.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such changes in the form, con-' struction and arrangement of arts as will not depart from the spirit oft e invention or the scope of the subjoined claims.
